Trina Solar, a global leader in solar energy innovation, unveiled its new n-type TOPCon Advanced technology on the first day of the International Solar Photovoltaic Power Generation and Smart Energy Conference and Exhibition (SNEC 2023) in Shanghai. The company also announced upgrades for the Vertex n-type series beginning next year, with the most powerful module in the series generating more than 700W.
Trina Solar announced that work has begun on Phase II of its 15GW monocrystalline silicon ingot project at its factory in Xining, Qinghai province and its 10GW n-type high-efficiency cell and 10GW n-type module project in Yangzhou, Jiangsu province. In addition, the company announced the establishment of a net-zero system by initiating the Environmental Product Declaration and carbon footprint certification for its Vertex N modules.
“The 210R rectangular cell, the selective boron emitter, the backside microstructure reflector, and the highly doped TOPCon structure with PECVD are four innovations key to the new-generation TOPCon Advanced technology,” said Dr. Chen Yifeng, associate vice president of technology at Trina Solar. “These have enabled the delivery of potential production efficiency of 26%, with a modular power output of up to 700W.”
“The Vertex N modules further reduce the levelized cost of energy for utility-scale solar development and will come to mass production next year,” he added.
At the conference, Trina Solar highlighted the company’s Vertex N 605W modules, designed for power stations in complex terrain and C&I solar stations, and their Vertex S+ modules capable of delivering 450W of power. Compared with regular n-type residential modules in the industry, these modules provide 5.88% more installation capacity for rooftops of the same area.
With the application of front-side full passivation contact cell technology, the mass production efficiency of Trina Solar’s n-type cells with TOPCon Ultra technology is forecast to exceed 27%. Implementing TOPCon tandem technology is expected to cause cell efficiency to surpass 30%.
In addition, Trina Solar’s Vertex n-type modules have drawn the accolades of third-party organizations such as China General Certification, RETC and PVEL for their reliability. The company’s projects in Qinghai and Jiangsu provinces are anticipated to serve as a foundation for continuous material supply for the company’s n-type modules and ensure worry-free product delivery. By year-end, Trina Solar’s module production capacity is forecast to reach 95GW while cell production capacity 75GW, with 40GW dedicated to n-type cells.
